.borough of Manhattan, city, county, and

State of New York, 'havelnvented certain new and useful Improvements in Three-Tie Step-Up Rail-Joints, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a side elevation of the meeting ends of two railroad rails showing the joint in position; Fig. 2 a transverse sectional view on the line IIII of Fig. l Fig. 3 a similar view on the line III III of Fig. 1; Fig. 4 a detail erspective-view of one of the splice bars; Fig. 5 a side elevation of the inner side of one of the splice bars in position on three ties, a ortion of the base support being corrugated Fig; 6' a detail view of one splice bar provided with a base support adapted to be extended entirely across the base of the rail; Figs. 7 & 8 are. cross-sectional views showing slightly diflerent forms of stiffening webs for the splice bars; Fig. 9 a detail bottom plan. view of a pair'ofsplice barsshowin anot or form of base supglolrt One of the objects of t 'sinvention is to provide a step-up rail joint with a base sup-,

portmidway its-ends and projecting 'under the adjoining ends of connected rails, said base support terminating shortof the ends of the-s lice bars. 9 I I I .A urther object of the-invention is to provide a three-tiestep up joint, that is to say, a

joint adated to be supported on three ties,

the joint etween the ra1 s being directly over one of the'ties.

' .fAnotherobject of the invention is to provide a step-up joint'which willalso serve as an anti-creeping device to prevent the creeping of the railroad rails and to hold the ties straight, that'is to say, perpendicular with reskpect to the railroad rai s.

ther objects of the invention relating more particularlyto details of construction will appear hereinafter.

The joint -is'composed of two members or splice bars 1 and 2, each of which consists of a web 3 provided at its upper edge with the inwardly and downwardly inclined bearing fa e 4 to support the head-of the larger rail. This web, from a point midway the ends of the splice bar to one.end thereof, isenlarged vertically or stepped-up to form the enlarged part 5 of the web, said enlarged portion being the base ofthe rails.

At a point midway the ends of the splice bar and integral with the flange 7, is formed an inward extending web 8 which stiifens the bar and forms a base support. This web 8, if found desirable, maybe extended in an desired direction below the base of the rai but it will, of course, be understood that if it be extended, as shown in Fig. 7, or in any similar manner, it will notiorm a base support, but will merely serve as a stilfenin' web. In most cases, however, said web wil be extended below the lower. edge of the flange-7, and is preferably of such length that its ends will abut against the sides of the ties and form an anti-cree ing device. As shown in the drawings, said web is of such length that its ends abut against the ends of the ties 8 and 8 the middle art of said Web resting upon an intermediate tie 8 thus forming an anti-creepin ventim the creeping of t 'e rails; The po'rtion'oi the base support/9, directly under the web 3, is considerably thinner than the portion 10, extending under the Web 5, that 1 portion-extending under web 5 being adapted to support the lighter rail and to hold it in position to bring its upper surface on a level with the upper surface of the'heavier rail 90 support 8, the inner edge thereof may be provided with a longitudinal rib or enlarge;

ment 11, as shown in Figs. 2- and 4, said rib- 1,00v

extending the full length of the base support and materially stiffening it and the splice bar asa whole. It will be readily manifest that the base supports may be transversely,

or longitmlinally. corrugated in order to 5 stiffen them, and to'save metal as shown at S in Fig. 5. It will, of course, be understood that the base support may be made entirely on one splice bar if desired, as indicated at 8 in Fig. 6, the other member of 110 device and pre- 'base of the rail, this broader part being adapted to extend under the other rail and to support the same so that under each rail end there will be a narrow portion of the base support extending inward from one splice bar and a broad base support extending in from the opposite splice bar. If desired, when the base support is in this form it Will be provided along its longitudinal edge with a stiffening enlargement'or bead.

Whenever it may be necessary to lace the smaller rail slightl out of line wit the vertical center of the larger rail in order to bring the flange side of the head in line with and flush with the flange side of the larger rail, the stepped-up art of the splice bar 'will be enlar ed latera ly sufliciently to pro erly space the smaller rail. In Fig. 4 tl ie stepped-u portion of the splice bar is shown as thus en arged at 5 Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1'. A step-up rail joint comprising two splice bars, each consisting of a longitudinal vertical web fornied'at its upper edge with a rail head supporting surface, saidweb being. vertically enlarged for a portion of its length to support the head of the smaller rail, each of said bars being formed at the lower edge of the web with an outward and downward extendin flangeadapted to fit overthe base of f the rai s, and a base support formed integral with the outer edge of said flange of one of the splice bars at the middle thereof and shorter. 1;

an the splice bars, that portion of the base support below the enlarged part of the web being corrugated and extending back under the flange and the web and adapted to fit under the rail, the upper surface of said base support below the enlarged portion of the web belng higher than the other part thereof,

' whereby the base of the smaller rail is raised above the base of the larger rail.

2. A stepup joint comprising two splice,

bars each consisting of a longitudinal vertical web formed at its upper edge with a rail head supporting surface, said Web being enlarged for a portion of its length to support the head of the smaller rail, each of said bars being formed at the lower edge of the web with an outward and downward extending flange adapted to fitover the base of therails, and a base support formed integral with the outer edge of said flange and extendin back under the flange and the web and adapted to fit under the rail, said base support being of equal thickness throughout and corrugated to form rail supports of different heights.

web formed at its upper edge with a rail head 1 supporting surface, said web being enlarged for a portion of its length to support the head of the small rail, each of said bars being formed at the lower edge of the web with an outward and downward extending flange adapted to fit over the base of the rails, and a base support formed integral with the outer edge of said flange and extending back under the flange and the web and adapted to fit under the rail, said base support being corrugated to form rail supports of different heights, and terminating short of the ends of the flange to adapt it to engage the ties and serve as an anti-creeping device.

4. A splice bar for step-up rail joints comprising a longitudinal vertical web formed at its upper edge with a rail head supporting surface, said Web being enlar 'ed for a portion I of its length to support t 1e head of the smaller rall, said bar being formed at the lower edge of the web with an outward and downward extending flange adapted to fit over the base of the rails, and a base su port integral with the outer edge of said flange extending back'under the flange and the vertical web, and adapted to fit under the rails, said base support being corrugated to form rail supports of different heights. 4

-5. A splice bar for step-up rail joints comprising a longitudinal vertical web formed at its upper edge with a rail head supporting surface, said web being enlarged for a portion .of its length to support the head of the smaller rall, said bar being formed at the lower edge ofthe'web with an outward and downward extending flange adapted to fit over the base of the rails, and a base support formed integral with the outer edge of said flange and extending back under the flange and the vertical web and adapted to fit under the rail, said base support being of uniform thickness of metal throughout and corrugated to form rail sup orts of different heights and terminating s ort-of the ends of the flange to adapt it to engage the ties and serve as an anti-creeping device.

6. A splicebar or connecting plate for rail way rail joints comprising a vertical longitudinal rail 'sup'portin web adapted along its upper edge to fit un er and support the head of the adjoining rails, an outwardly and downwardly inclined flan e formedintegral with the lower edge of said web and adapted to fit over the base of the rail, and an inward turned base support formed integral with the free edge of sai flange and extending under the flange and. the web and adapted to ex tend under and supportthe abutting ends of the rails to be connected, a portion of said base support being in width substantially equal to the width of the base of the rail, the

emainder of said base support being very splice bars eac 1 of which is formed with a narrow and being adapted to extend only slightly under the base of the rail, said broad and narrow portions of the base support be ing connected together substantially midway between the ends of the splice bar.

7. A step up rail joint comprising two splice bars eac i of which is formed with a vertical longitudinal supporting web adapted to support the heads of the rails, a ortion of said web being ste' ped-up vertical y to support the smaller rail an outwardly and down- \vardiy inclined flange formed at the base of said web, said flange being equal in length to the web and adapted at its ends to rest on the ties, and a short stiflening web and base su port formed integral withthe free edge of t e' flange and extending across the line of the enlargement of the'web, the upper surface of said base support being of different heights to sup ort the rails and terminating short of the ends of the flange. v
